Read sysvol

I have the sysvol folder from a server and I want to read all the policies inside (every policy has inside Adm, Machine,User folder and a GPT.ini file). Is there any tool I could use in order to generate a report?

The GPMC (Group Policy Management Console) should enumerate each of these, and provide "plain english" views of the various enabled settings. I've used these views for printing to read and keep a log of my GP's.

Although, reading what you've written, if you don't have the server itself, where this is an active SYSVOL directory, you might not have luck with the GPMC, unless you can copy the policies onto a test server's SYSVOL directory. Not sure how this will react though.
